Product introduction
The non-toxic capsule is used as a new type of equipment for gas water isolation. Combined with the characteristics of fire fighting, living and production water, it is a new generation of products with advanced foreign level. It adopts microcomputer programmable control technology. According to various situations of water supply pipe network and water source, it controls and regulates various complex works by microcomputer. When it works, it starts the make-up water pump, the water chamber enters, the water pressure rises, the gas in the air chamber is compressed, and the water pump starts at the set high pressure Power stop: due to pipeline leakage or gradual decrease of fire water pressure, when the water pressure drops, the gas in the air chamber expands, the diaphragm shrinks, pressing the water outlet of the water chamber, and the make-up pump starts at the set low pressure, so that the water pump can be controlled by the electric contact pressure gauge and the automatic electric control box to achieve the rated pressure and continuous water supply, realizing the intelligent water supply.
Product characteristics
1. The fire-fighting pressure stabilizing equipment is a special pressure stabilizing equipment designed and manufactured according to the national building standard design atlas 98s205. The equipment is composed of diaphragm type air pressure tank, fire booster pump, electric control box, instrument and pipeline accessories. Mechanical and electrical integration, compact structure, good reliability, automatic and efficient operation of water pump, no need for special personnel to watch, significant energy-saving effect, eliminate secondary pollution, improve water quality, small start-up and stop impact, greatly improve the service life of relevant equipment, at ordinary times, the pressure of the pipe network is stabilized at the set value by the stabilized pressure pump group, and the main fire pump automatically starts to put out the fire in case of fire. And equipped with vibration isolator, without pre buried foot hole.
2. The valves used in the equipment are all domestic high-quality brand-name products, which can ensure the reliable operation of the equipment. The core components of the fire control system can choose different brands according to different needs of users or different application occasions. The main components of the electrical system are products of domestic or imported famous brand enterprises, with reliable quality and stable operation. High quality electrical components ensure that the control system has a higher reliability, greatly reducing the failure rate of the equipment, and improving the service life.
3. The equipment has automatic protection and failover functions. Two fire pressure stabilizing pumps (one can be set according to the design requirements) are one for use and one for standby. In case of any pump failure (electrical failure or hydraulic failure), the standby pump can be started.
4. Can select tank, pressure stabilizing mode, control function and connect with fire control center according to the needs of customers.
5. The equipment adopts diaphragm type air pressure water tank, which can be used for a long time with one-time inflation, and the air and water are not contacted, so as to ensure the water quality is free from external pollution, and can automatically eliminate the water hammer and noise in the pipe network
Selection of equipment water pump
1. When the water pump of the fire-fighting pressure stabilizing equipment directly absorbs water from the municipal water supply network, the minimum water pressure of the municipal water supply network shall be taken into account when calculating the head of the water pump, and the efficiency and overpressure of the water pump shall be checked with the maximum water pressure of the municipal water supply network. The water pump of the fire-fighting pressure stabilizing equipment shall meet the following requirements: low noise and energy-saving centrifugal pump shall be adopted; two or more pumps shall be set; the overflow part of the water pump shall be made of stainless steel; the model and number of the water pump shall be determined comprehensively by the design, and the small water pump suitable for the low water consumption shall be configured if the water consumption is unbalanced and lasts for a long time.
2. For the water pump of fire-fighting pressure stabilizing equipment, the water output of the water pump shall be close to the design flow of water supply as much as possible. When there are local measured data of water supply design flow, the design flow of water supply should be determined according to the measured data.
Function and application scope of equipment
This equipment can maintain the fire fighting pressure of the water fire-fighting pipe network. In case of fire, the water fire-fighting equipment can immediately spray out the full water column to win the initial fire fighting time of more than 30 seconds for the alarm linkage start of the large fire pump, until the main fire pump is started at full load. Because the equipment can always maintain the pipe network pressure, the pipe network will not be started without air, the large fire pump will not choke the pipe network, and the pipe network will not vibrate DANGER.
The fire pressure stabilizing equipment is applicable to the pressure increasing (stabilizing) of various fire water supply systems or other industrial pressure stabilizing systems, such as fire hydrant water supply system and automatic sprinkler system, which have pressure increasing requirements for multi-storey and high-rise buildings.
